The average speed display is somewhat confusing.
Is there a starting point to calculate the average speed or does the calculation span the lifetime of the car? Is it possible to reset this display and start at a certain point? For example, if I enter a freeway and drive there for several hours or so and the display can be set to zero at the start, shouldn't it display the average highway speed along with the respective mpg figure and not take all the stops and slow speed before the highway entry into account?
Thanks,
Ed
